Description

Technical Field

[0001] This utility model relates to a protective structure for pipelines in a low-temperature cold storage. Background Technology

[0002] Arcti c Fox aspirating smoke detectors feature high sensitivity and active aspirating detection, overcoming the impact of strong air convection caused by the refrigeration unit on the detector. They employ Arcti c Fox airflow deceleration diaphragm and WTH anti-freeze clip technology, which play a significant role in de-icing and preventing frost from clogging the intake (sampling hole).

[0003] The existing antifreeze clip consists of an outer layer of ABS material and an inner layer of silicone material. The inner layer has air holes corresponding to the sampling holes. It is clamped onto the sampling tube by the flexible outer layer. By drawing in air, the silicone inner layer expands and breaks the frost, thus achieving the function of de-icing. However, in actual use, the air holes and sampling holes need to be connected to each other to ensure that air can enter the sampling tube normally. During installation, the staff needs to open the outer layer and visually observe that the air holes and sampling holes are aligned before clamping. After installation, the inner layer needs to be pressed. When part of the inner layer is embedded in the sampling hole, it is considered that the installation is complete. Otherwise, the outer layer needs to be removed and readjusted. The operation is relatively troublesome and the installation efficiency is low, which adds difficulties to the subsequent maintenance of the sampling tube and antifreeze clip.

[0004] Therefore, we propose a protective structure for low-temperature cold storage pipelines. Utility Model Content

[0025] Example 1

[0026] Reference Figure 1-6 As shown, a protective structure for low-temperature cold storage pipelines includes...

[0027] The antifreeze clamp mechanism 101 includes an outer clamp 1 and an inner film 4 that can fit against the outer wall of the sampling tube; the outer clamp 1 has a second through hole 7 that matches the corrugated tube 6.

[0028] A through hole 5 is provided on the inner film 4 for connecting with the sampling hole on the sampling tube.

[0029] It also includes a mounting unit 102, which is disposed on the inner film 4 and corresponds to the first through hole 5. The mounting unit 102 extends into the sampling tube from the sampling hole and pre-positions the inner film 4 before the outer clamp 1 tightens and fixes it, ensuring that the first through hole 5 is aligned with the sampling hole. The mounting unit 102 includes a connecting rod 13 and multiple positioning crossbars 14 disposed on the connecting rod 13. One end of the connecting rod 13 is fixed at the first through hole 5, and the multiple positioning crossbars 14 are disposed at the other end of the connecting rod 13 and can be inserted into and held in the sampling hole. The mounting unit 102 also includes a corrugated tube 6 disposed on the inner film 4 and communicates with the first through hole 5. The connecting rod 13 is housed in the center of the corrugated tube 6. The mounting unit 102 also includes a support plate 12, which is disposed in the air inlet 11, and the bottom end of the connecting rod 13 is connected to the support plate 12.

[0030] In this system, the connecting rod 13 serves as the main support and guide shaft, while the positioning crossbar 14 acts like a "barb" or "anchor point." Its diameter is slightly larger than the sampling hole or it possesses a certain degree of elasticity. After insertion, it provides clamping force, preventing accidental displacement of the inner film before tightening the outer clamp, thus ensuring the stability of the pre-positioning. Furthermore, before installing the outer clamp 1, the operator can insert the positioning crossbar 14 into the sampling hole. This action directly determines the circumferential and radial position of the inner film 4 relative to the sampling tube. During clamping, a certain amount of friction or mechanical interference temporarily fixes the inner film 4, preventing it from easily shifting during subsequent tightening operations. This ensures that the first through hole 5 and the sampling hole are always precisely aligned, achieving a fundamental shift from "alignment by visual observation" to "forced alignment by physical and mechanical means."

[0031] Furthermore, the design of housing the connecting rod 13 within the center of the bellows 6 resolves the conflict between the new and existing functions. The bellows 6 is a conventional de-icing component in the field (breaking ice through its expansion and contraction). Placing the connecting rod 13 within its center efficiently utilizes the inherent hollow structure of the bellows without adding extra radial dimensions, ensuring product compactness. At the same time, by housing the connecting rod 13 internally, the two functions do not interfere with each other; the positioning function of the connecting rod 13 is unaffected, and the flexible expansion and contraction of the bellows 6 is not hindered.

[0032] Furthermore, the support plate 12, acting as a "mounting flange," provides a solid mounting base for the connecting rod 13, ensuring the stability of the entire positioning structure under stress (such as insertion or clamping). Moreover, the support plate 12 is positioned within the air inlet 11 rather than completely blocking it, thus demonstrating that it combines support and airflow functions, ensuring the effectiveness of the intake channel.

[0033] Therefore, this embodiment forms an independent and efficient mechanical positioning system through the connecting rod 13 and the positioning crossbar 14, which solves the core problem of installation and focusing. At the same time, the ingenious design of embedding the connecting rod 13 into the bellows 6 ensures that the addition of new functions will not sacrifice the performance of the original de-icing function and the overall compactness of the product structure.

[0034] The bottom of the bellows 6 is provided with a retractable folded layer 10, and an air inlet 11 is opened in the center of the folded layer 10. Specifically, the bellows 6 and the folded layer 10 together form a retractable airbag structure. When the detector inhales air, a negative pressure is generated inside, causing the airbag to contract and allowing outside air to rush in. When the inhalation pauses, the airbag rebounds. This "breathing" action causes the inner film 4 attached to the sampling hole to move slightly, effectively breaking up any frost that may form and preventing blockage.

[0035] Positioning posts 9 are symmetrically distributed on the outer surface of the inner film 4, and positioning holes 8 that are adapted to the positioning posts 9 are opened on the outer clamp 1; operating plates 2 are symmetrically distributed on the outer surface of the outer clamp 1. Specifically, after the mounting unit 102 completes the initial alignment, when the outer clamp 1 is closed, the positioning posts 9 will be inserted into the positioning holes 8 to ensure that there is no circumferential displacement between the inner and outer layers, further consolidating the alignment state, while the operating plate 2 provides a force point, making it easy to manually pry open and tighten the outer clamp 1, which has a certain rigidity, facilitating the installation operation.

[0036] Working principle: During installation, the operator first aligns the positioning crossbar 14 at the front end of the mounting unit 102 with and inserts it into the sampling hole on the sampling tube. Since the size design of the positioning crossbar 14 matches the sampling hole, the inner film 4 can be pre-positioned after insertion, ensuring that the No. 1 through hole 5 on it is precisely aligned with the sampling hole. Then, the outer clamp 1 is closed, and the positioning hole 8 on it engages with the positioning post 9 on the inner film to prevent circumferential rotation. Finally, the clamp is tightened to complete the installation. The whole process does not require repeated adjustments. During operation, the negative pressure generated by the suction detector causes the bellows 6 and the folded layer 10 to contract, and external air is drawn in through the air inlet 11. When the negative pressure disappears, the bellows and the folded layer rebound. This continuous "breathing" effect causes the inner film 4 to move slightly, effectively breaking up the frost covering the sampling hole and preventing blockage.

[0037] Example 2

[0038] Reference Figure 7 The difference from Embodiment 1 is that the inner wall of the outer clamp 1 is provided with symmetrically distributed compensation elements 15, each including an anti-slip adhesive patch 16 with multiple anti-slip stripes. Specifically, the compensation elements 15, the anti-slip adhesive patch 16, and the anti-slip stripes prevent slippage between the clamp and the pipe, leading to loosening or even detachment, under conditions of cold storage vibration or drastic temperature changes. Furthermore, the elasticity of the adhesive material fills any small gaps that may exist between the clamp and the outer wall of the pipe, providing better clamping force and sealing effect, especially suitable for conditions where the pipe surface is uneven or has slight dimensional deviations. Embodiment 2, while possessing all the advantages of Embodiment 1, provides higher reliability and wider applicability.

[0039] Working Principle: Based on the working principle of Example 1, Example 2 adds a compensation component 15, which plays an important role. When the outer clamp 1 is tightened, the anti-slip adhesive 16 on its inner wall is tightly attached to and pressed against the outer wall of the sampling tube under the action of the bolt clamping force. The elasticity of the adhesive itself can compensate for the tolerance and roundness deviation of the pipe size, ensuring that the clamping force is evenly distributed. The anti-slip stripes on the surface greatly increase the static friction with the pipe surface, like a built-in anti-slip washer, which can effectively resist stress relaxation caused by equipment vibration or temperature changes, prevent the clamp from loosening or slipping during use, and thus ensure the long-term stability and airtightness of the entire protective structure in harsh low-temperature environments.
